After years of trying different methods of naming and sequencing hundreds of Internet Explorer Favorites, here is the method I have settled upon. Rename the top level folders with a two digit prefix (starting 01, 03 etc.) followed by a space. I have โ01 Financeโ, โ03 Forumsโ through to โ53 Artโ. Not all, but some subfolders and individual websites are prefixed in the same way. Leave gaps in the numbering system to allow insertions and keep the names as short as possible, otherwise a wider pane is needed to display them. As new ones are saved, just right-click or press and hold and choose โSort by nameโ which puts them in alphanumeric sequence.
This is a one-off labour-intensive procedure, but it is worthwhile doing.
